TECHNICAL FIELD

The present invention relates to an antitumor formulation comprising a combination of a biphenyl compound or a salt thereof and one or more other antitumor agents, and an antitumor effect potentiator for the one or more other antitumor agents.

BACKGROUND ART

Histone methylation modification is one of the epigenetic mechanisms, which regulate gene expressions. Histone methylation modification regulates various processes including cellular maintenance, growth, and differentiation.

LSD1 (KDM1A), one of the enzymes that regulate histone methylation modification, is an FAD (flavin adenine dinucleotide)-dependent histone demethylase, and mainly demethylates the lysine residue at position 4 (K4) and the lysine residue at position 9 (K9) on histone H3 (Non-patent Literature (NPL) 1). With such functions, LSD1 is believed to positively or negatively regulate various gene transcriptions, and regulate stem cell self-renewal and cell differentiation in each normal tissue.

In general, abnormalities in cell self-renewal capacity or differentiation are believed to lead to cell cancerization. Thus, aberrant control of LSD1, which plays a key role in these processes, can possibly cause cell cancerization. In fact, in terms of various solid and blood cancers, many reports have been made regarding the correlation of overexpression of LSD1 and their prognosis (NPL 2). Further, in cell lines from carcinomas or in non-clinical models, LSD1 inhibition has been reported to have resulted in induction of cellular differentiation, growth inhibition, and an in vivo antitumor effect (NPL 3 and NPL 4), which strongly suggests that LSD1 serves as one of the important target molecules in cancer therapy. These carcinomas in which LSD1 is involved, such as small-cell lung cancer (SCLC) and acute myelocytic leukemia (AML), have an extremely short lifetime, and existing therapeutic methods cannot achieve a satisfactory therapeutic effect.

Accordingly, LSD1 inhibitory drugs are expected to provide effective therapeutic means based on novel mechanisms to treat intractable cancers, for which no therapeutic methods currently exist.

Further, according to some reports, LSD1, which is involved in neuron programs and functions, can also possibly serve as a target in the treatment of diseases other than cancers, such as Alzheimer's disease, Huntington's disease, Rett syndrome, and other cranial nerve diseases (NPL 2); Herpesvirus infections, in which LSD1 function has been implicated (NPL 5); and sickle cell diseases (NPL 6).

There are some reports regarding antitumor effects of combinations of LSD1 inhibitors with other antitumor agents. For example, an antitumor effect of a combination of LSD1 inhibitor SP2509 with histone deacetylase inhibitor panobinostat on acute myelocytic leukemia has been reported (NPL 7). In addition, an antitumor effect of a combination of LSD1 inhibitor INCB059872 with all-trans retinoic acid (ATRA) on acute myelocytic leukemia has been reported (NPL 8).

At room temperature, PdCl₂(PPh₃)₂ (398 mg) and tripotassium phosphate (4.513 g) were added thereto. After nitrogen substitution and degassing, the mixture was stirred at 100° C. overnight. The reaction mixture was passed through Celite, and the solvent was distilled off. The residue was purified by silica gel column chromatography (mobile phase: hexane/ethyl acetate), and the solvent was distilled off. THF (45.0 mL) and 12 N hydrochloric acid (45.0 mL) were added to the residue, followed by stirring at room temperature for 2 hours. MTBE and water were added thereto for partition. After the organic layer was washed with saturated brine and dried over anhydrous sodium sulfate, the solvent was distilled off. The residue was crystallized from diethyl ether/hexane to give 4-[7-bromo-6-fluoro-1-(2-hydroxy-2-methyl-propyl)benzotriazol-5-yl]-3-(4-cyano-3-fluoro-phenyl)benzoic acid.

Step 6

Test Example 1: Measurement of LSD1 Inhibitory Activity (In Vitro)

The conditions for measuring inhibitory activity of compounds against LSD1 activity were determined with reference to a document available from the website of PerkinElmer (U-TRF #38) and a patent of GlaxoSmithKline (WO2012135113).

To measure the inhibitory activity, first, the Example compound was serially diluted in dimethylsulfoxide (DMSO). Sequentially, the serially diluted solution of the Example compound in DMSO (final concentration of DMSO: 5%) and human LSD1 protein (Abcam, ab80379) were added to a reaction buffer (25 mM Tris-HCl (pH 7.5), 50 mM KCl, 2 mM CHAPS, 1 mM DTT, 0.02% BSA). The mixture was preincubated at 25° C. for 30 minutes. Thereafter, a H3K4 (Me1)-biotin-labeled peptide (Anaspec #64355) (final concentration: 200 nM) was added thereto and reacted for 60 minutes. Tranylcypromine (final concentration: 3 mM) was then added thereto to terminate the reaction. Thereafter, a detection solution containing an Eu-labeled anti-H3K4 antibody (PerkinElmer, TRF0404) and Streptavidin Alexa Fluor 647 (Thermo Fisher Scientific, S21374) was added thereto, and the mixture was allowed to stand at room temperature for 1 hour. Finally, the intensity of fluorescence under the excitation light with a wavelength of 337 nm was measured with a PHERAstar FS (BMG Labtech) at two wavelengths: 620 nm and 665 nm. The demethylation level was calculated from the ratio of the fluorescence intensity at the two wavelengths, and the compound concentration at which demethylation was inhibited by 50% was defined as IC50 (nM). The following tables show the results.

The results of the test clarified that the biphenyl compound represented by Formula (I) exhibits LSD1 inhibitory activity.

Test Example 2: Cell-Growth Inhibition Test

Under the following conditions, an in vitro cell-growth inhibition test was performed with respect to HEL cells (human acute myelocytic leukemia cell lines), NCI-H1417 cells (human small-cell lung cancer cell lines), and NCI-H146 cells (human small-cell lung cancer cell lines).

HEL cells (JCRB, Cat #: JCRB0062), NCI-H1417 cells (ATCC, Cat #: CRL-5869), or NCI-H146 cells (ATCC, Cat #: HTB-173) cultured in a 10% FBS-containing RPMI1640 medium (Thermo Fisher Scientific, Cat #: A10491-01) were seeded in a 96-well flat-bottom microplate (Thermo Fisher Scientific, Cat #: 165305) so that each well contained 1500 HEL cells (100 μL), 5000 NCI-H1417 cells (100 μL), or 1200 NCI-H146 cells (100 μL). The Example compound was serially diluted in dimethylsulfoxide to a concentration that was 500 times higher than the final concentration. The serially diluted Example compound or dimethylsulfoxide alone was added to a 10% FBS-containing RPMI1640 medium to a concentration that was 2 times higher than the final concentration, and the resulting product was added in an amount of 100 μL to each well of the culture plate containing HEL cells, NCI-H1417 cells, or NCI-H146 cells, so that the final concentrations of the Example compound were 3000, 1000, 300, 100, 30, 10, 3, 1, 0.3, 0.1, 0.03, and 0.01 nM. The final concentration of dimethylsulfoxide was adjusted to 0.2%. The cells with the Example compound or with dimethylsulfoxide alone were cultured at 37° C. in a 5% carbon-dioxide-containing incubator for 5 days (HEL cells) or 10 days (NCI-H1417 cells and NCI-H146 cells). After culture, the plate was allowed to stand at room temperature for 30 minutes, and 100 μL of the supernatant was removed from each well to leave 100 μL of the cell culture solution. To each well containing the remaining 100 μL of the cell culture solution, the same amount of CellTiter-Glo 2.0 Assay (Promega, Cat #: G9242) was added. The microplate was shaken with a plate mixer for 1 minute and then allowed to stand in a dark place for 10 minutes. Thereafter, the luminescence intensity of viable cells in each well was measured using a microplate reader (PerkinElmer, EnSpire). The cell growth rate was determined in accordance with the following equation, and the concentration at which the cell growth rate was 50%, i.e.; the concentration of each test compound at which the cell growth was inhibited by 50% (IC50 (nM)) was determined.

Cell growth rate (%)=T/C×100

T: The luminescence intensity in a well to which the test compound was added (count per second) C: The luminescence intensity in a well to which dimethylsulfoxide alone was added (count per second)

The results of this test revealed that the biphenyl compound represented by Formula (I) exhibits in vitro cell growth inhibitory effects, and that this compound not only inhibits the activity of recombinant human LSD1 protein but also inhibits cancer cell growth, suggesting that this compound is useful as an antitumor agent.

Test Example 3: Antitumor Effect Test Using NCI-H146 Cells (Human Small-Cell Lung Cancer Cell Lines)

NCI-H146 cells, 3.5×10⁶ cells (100 μL), were subcutaneously implanted into BALB/cAJcl-nu/nu mice, and mice with a tumor volume within a range of 100 to 300 mm³ were divided into groups so that the groups had a uniform average tumor volume. To 5 mice in each group, a vehicle (0.5% hydroxymethylpropylcellulose containing 0.1 N HCL) or each Example compound was orally administered. The administration was performed once a day for 21 consecutive days (Example compound 41) or 28 consecutive days (Example compounds 37, 161, 166, 175, 176, and 177). The major axis and the minor axis of each tumor were measured twice a week with an electric caliper to calculate the tumor volume (TV). According to the tumor volumes thus obtained, a relative tumor volume (RTV) and a relative tumor volume change (T/C (%)) were calculated. The TV, RTV, and T/C (%) were calculated using the following equations.

Tumor volume TV (mm³)=(major axis, mm)×(minor axis, mm)×(minor axis, mm)/2

Relative tumor volume RTV=TV/(TV on the grouping day)

T/C (%)=(average RTV of administration group)/(average RTV of vehicle administration group)×100.

The table below shows the results.

The final measurement day was the day following the final administration day. The biphenyl compound represented by Formula (I) showed an antitumor effect on the above models for efficacy evaluation, and the percentage of body weight reduction on the final measurement day was less than 20% of the body weight before administration (day 0).

The results revealed that the biphenyl compound represented by Formula (I) or a salt thereof exhibits excellent LSD1 inhibitory activity, shows a cancer cell growth inhibitory effect, has low toxicity, and is orally administrable. Therefore, the biphenyl compound represented by Formula (I) or a salt thereof is useful as an agent for preventing and/or treating cancer.

Cells were seeded at 20 μL/well in a 384-well culture plate (Corning). The plate seeded with cells was cultured in an incubator set at 37° C. and 5% CO₂. On the day of seeding, drug solutions containing a combination of one of the biphenyl compounds and one of other compounds having an antitumor effect mixed at various concentrations were each added to the cells. Specifically, using an RPMI-1640 medium containing 20% FBS (ATCC-formulated medium) or an RPMI-1640 medium containing 10% FBS, 10 ng/mL IL-3, and 50 μM 2-ME, ten-step serial dilutions (including 0 nM) of the biphenyl compounds (Example compounds 37, 41, 166, 177, 214, 273, and 285) were prepared, and eight-step serial dilutions (including 0 nM) of other compounds having an antitumor effect were prepared. Solutions in which the same amount of serial dilution of each compound was dispensed were mixed at a ratio of 1:1, and a total of 80 mixed drug solutions were prepared with brute-force combinations. The table below shows the maximum concentration (expressed as the final concentration) and geometric ratio of each compound. Each of these mixed solutions was added to the plate at 5 μL/well (N=4), and further cultured at 37° C. under 5% CO₂ conditions for 10 days. Ten days later, CellTiter-Glo 2.0 Assay (Promega, Cat #: G9242) was added at 25 μL/well, and chemiluminescence was measured with a plate reader (EnSpire (registered trademark) Multimode Plate Reader, PerkinElmer Japan Co., Ltd.).

The effect potentiated by the combined use of drugs was evaluated according to the methods described in known documents (Trends Pharmacol. Sci., 4, 450-454, 1983; Pharmacol Rev., 58 (3), 621-81, 2006).

Specifically, normalized cell viability T/C (treatment/control ratio, %) was determined by comparing the cells treated with each single agent of the biphenyl compounds and other compounds having an antitumor effect with control cells. From the obtained T/C values, the half maximal inhibitory concentration (IC50) of each drug was determined by a curve fitting regression analysis tool using a regression analysis tool XLfit 5.3 (IDBS Ltd.).

The IC50 ratio of each single agent was calculated by the following equation.

IC50 ratio=[IC50 of biphenyl compound]:[IC50 of other compound having antitumor effect].

Regarding the concentration ratio combination of two compounds actually used in the experiment, the half maximal inhibitory concentration (ED50) when both compounds were used in combination was determined using their T/C. The combination index (CI) and fraction affected (Fa) in ED50 were determined. For the calculation of CI, median effect analysis software CalcuSyn 2.0 (CalcuSyn, Inc.) calculating the median-effect method was used.

The effect of combined use was determined as shown in the following table (Pharmacol Rev., 58 (3), pp. 621-81, 2006).

These results indicated that the antitumor effects of the biphenyl compounds were synergistically potentiated when used in combination with an antimetabolite (cytarabine, decitabine, or azacitidine), an all-trans retinoic acid (tretinoin (ATRA)), or an antitumor antibiotic (daunorubicin).

Test Example 5: Combination of Biphenyl Compounds and Other Antitumor agents Using Human Small-Cell Lung Cancer Cell Line (In Vitro)

The following tables show the source of reagents, the source of tumor cell lines, the media used, and the number of seeded cells.

Cells were seeded at 100 μL/well in a 96-well culture plate (NUNC). The plate seeded with cells was cultured in an incubator set at 37° C. and 5% CO₂. On the day after seeding, drug solutions containing a combination of biphenyl compounds and other compounds having an antitumor effect mixed at various concentrations were each added to the cells. Specifically, using an RPMI-1640 medium containing 10% FBS or an F-12K medium containing 10% FBS, eight-step serial dilutions (including 0 nM) of the biphenyl compounds (Example compounds 37, 166, 177, and 273) were prepared, and eight-step serial dilutions (including 0 nM) of other compounds having an antitumor effect were also prepared. Drug solutions in which the same amount of serial dilution of each compound was dispensed were mixed at a ratio of 1:1, and a total of 64 mixed drug solutions were prepared with brute-force combinations. The table below shows the maximum concentration (expressed as the final concentration) and geometric ratio of each drug. Each of these mixed drug solutions was added to the plate at 100 μL/well (N=1), and further cultured at 37° C. under 5% CO₂ conditions for 10 days. Ten days later, 100 μL of the culture supernatant was removed from each well to leave 100 μL of the cell culture solution. CellTiter-Glo 2.0 Assay (Promega, Cat #: G9242) was added at 100 μL/well to the remaining 100 μL of the cell culture solution. The chemiluminescence measurement was the same as in Test Example 4.
